AI Checker · 6 tools
Detect AI-generated text and images, flag ChatGPT and GPT-4 writing, check for plagiarism, and confirm whether content was written by a human or a machine.
An AI checker is a tool that estimates whether a piece of text or an image was generated by AI rather than a person. It scores content for signals like predictability (perplexity) and uniform phrasing, then reports a percentage or a verdict. Many bundle plagiarism checks, so the category overlaps with the ChatGPT and GPT-4 detectors used in schools and publishing.
Screen student essays and submissions for undisclosed AI writing before grading.
Verify that freelance or submitted articles are original human work, not AI drafts.
Scan their own drafts to see what a detector will flag before submitting.
Audit large batches of articles for AI text and duplicate content at scale.
Most text detectors run the writing through a language model and measure how predictable each word is — AI tends to pick the statistically likely next word, giving low perplexity and burstiness. The tool turns those signals into a probability that the passage is machine-written. Image checkers instead look for generation artifacts and metadata, and none of these methods is definitive.
